JTS.orthodromicDistance介绍

[英]Computes the orthodromic distance between two points. This method:

  1. Transforms both points to geographic coordinates (latitude,longitude).
  2. Computes the orthodromic distance between the two points using ellipsoidal calculations.

The real work is performed by GeodeticCalculator. This convenience method simply manages a pool of pre-defined geodetic calculators for the given coordinate reference system in order to avoid repetitive object creation. If a large amount of orthodromic distances need to be computed, direct use of GeodeticCalculator provides better performance than this convenience method.
[中]计算两点之间的正射距离。此方法:
1.将两个点转换为地理坐标(纬度、经度)。
1.使用椭球体计算计算两点之间的正射距离。
实际工作由大地测量计算器完成。这种方便的方法只是为给定的坐标参考系管理一组预定义的大地测量计算器,以避免重复创建对象。如果需要计算大量的正射距离,直接使用大地测量计算器比这种方便的方法提供更好的性能。
